Here is the good list i've got from updating to miui 9
- idk but the speaker seems louder now
- charges faster
- battery life is improved a lil bit
- faster and lighter ui
- split screen
- native screen recorder
And yes as someone below said, I don't think I need to upgrade my phone as well. Perhaps I'll be upgrading when android 9/10 is out

I am downloading this update 393 MB and need to know about battery life. Tysm

after the miui9 and android nougat update, this phone is blazing termendously superb. planning on changing to mi5, but nope, this phone is still the best bang for buck, can do split screen, can use playstore on china rom, no need to flash, xiaomi still update this phone even it few years old already. maybe because of the sd808. 9/10. if got fingerprint will give 10/10. perfect as a backup phone too. battery still rock after several years of usage

Mi4C is the best budget phone for me. In terms of the screen 441 ppi man! Oh come on.
And I have Nougat on it, and damn its super sophisticated. The camera itself is so much betteeeer than samsung, even iphone 6.
Cause I love 5.0 inch phone its not make my arms hurts instead of using 5.5 inch phone.

The battery life also perfect, it could last for more than 12 hours (depend on the phone usage). But some of my tips to not activate background process and turn on batteru saver could really help to extend battery Life.
